Abstract

The vortex street of a turbine blade profile (VKI-1, 58 mm chord length) was investigated by particle image velocimetry (PIV) and laser vibrometry in a Mach number range between 0.26 and 0.78. While the laser vibrometer (LV) measured the frequency of the density fluctuations in the wake and around the profile, PIV helped to clarify the vortex shedding process. The recordings done by the LV resulted in detailed frequency data of vortex shedding when Mach number and Reynolds number were varied, while the results obtained by PIV enabled a phase resolved measurement of the flow field during vortex shedding.
